The issue of increasing tropospheric Ozone and, more in general, of photochemical smog
is of growing in importance. It is, however, a problem of extreme complexity, involving both atmospheric
diffusion processes and complex chemical reactions. We present a study carried out to
examine the evolution of the Ozone concentration fields and the effects of meteorological conditions
on atmospheric pollutant concentrations in an industrial zone, namely Falconara, located on
the central Adriatic coast of Italy. The aim of our study was to evaluate the possibility of assessing
the diurnal evolution of air pollutants by introducing the Representative Day technique in order to
obtain information on chemical reactions and air pollution in poorly monitored areas. The use of the
Representative Day allows the compilation of large amounts of data in a compact format that will
supply meaningful information on the whole data set.
